0.33 gm of iron in 100 gm of heamoglobin
molar mass of heamoglobin is 67,200 gm
suppose x gm of iron is present in 67,200gm of Hb
therefore,
0.33 - 100
x - 67200
0.33×67200/100 = 221.76 gm of iron
now, mass of 1 atom of Fe =56
some atoms of mass of Fe= 221.76
let those some atoms be y
therefore,
1 - 56
y - 221.76
1×221.76/56 = 3.96 atoms which is approximately by round off is 4.0
answer: 4 atoms of iron
